March 2005

SCAPA’s annual meeting will be held on May 5, 2005 in New Orleans, LA. This meeting is being held in conjunction with EMI-SIG’s annual meeting (May 2-4).

SCAPA has been active on a number of fronts since our last news report. One major activity involves SCAPA’s outreach to members of the DOE biosafety community. Currently, SCAPA’s membership is well versed on potential radiological hazards, chemical hazards, and consequence assessment modeling. Unfortunately, there are few SCAPA members with comparable expertise on potential biological hazards. SCAPA’s outreach to the biosafety community is intended to help fill in this gap. For the biosafety community, involvement in SCAPA would provide a framework for the biosafety officers to meet, share information about their discipline, and learn about related consequence assessment capabilities and activities.

As part of this outreach, biosafety officers from each major DOE Site have been contacted by SCAPA. The biosafety officers will be meeting with Jim Powers (DOE/NA-41) the day before the SCAPA meeting to discuss new DOE orders that cover biosecurity. The biosafety officers will then attend SCAPA’s annual meeting where there will be several presentations and a panel discussion on biosafety and related consequence assessment modeling topics.

New software quality assurance standards will soon be issued by DOE. DOE Order 414.1c and DOE Guide 414.1-4 (both currently released in draft form) will apply to software used to make safety and safety-related decisions. The new Order and Guide may have substantial impacts on the development, selection, and use of consequence assessment models and other safety-related products. A presentation on this topic will be made by the DOE Office of Quality Assurance at the upcoming SCPAPA meeting. This will be followed by a discussion on how the new Order and Guide are being implemented at selected sites. When the Order and Guide are released in final form, the Consequence Assessment Modeling Working Group will begin to develop guidance on the implementation of these quality assurance requirements for our consequence assessment models.

Development work on TEELs and HCNs continues. New chemicals are being assessed in preparation for the next revision of the TEEL database and questions involving UF 6 emissions and chemical refrigerants have been recently addressed. Functional improvements have also been made to the new TEEL database. A workshop is being developed to provide training to Site personnel on the use of TEELs and HCNs. An abridged version of this workshop, “Developing and Using Chemical Protective Action Criteria (PACs)”, will be presented a few days before the SCAPA meeting (as part of EMI-SIG program). In addition, work is planned to begin within the next few months on a project that will enhance the technical documentation for TEELs.

NARAC and the Savannah River Site were both involved in real-time modeling of the chlorine releases that occurred during January’s rail accident in Graniteville, South Carolina. Presentations on their work will be made at the SCAPA meeting. NARAC will also make presentations on recent enhancements to their NARACweb system, the development status of iClient 2.0, and improved methods for sharing information.
